    Seq-write is poor on Raid with Write-back?

    litfal

      I have ST3000DM001 x2, and I use them to build Raid0 / Raid1

      But the Seq-write is poor when I turn on Write-back in IRST.

       

      Raid1 Write-back ON:

      Raid 1 Write-back off:

      13. RAID1_CA_NCF_NOIWB.PNG

       

      Raid 0, WB on:

      04. RAID0_NCF_IWB.PNG

      Raid 0, WB off:

      03. RAID0_CA_NCF_NOIWB.PNG

       

      Environment:

      OS: Windows 8 Pro x64

      RAID Option ROM: 11.2.0.1527

      Driver: 11.7.0.1013

      MB: Asrock Z77 fatal1ty

      Disk: ST3000DM001 1CH166 CC44x2

       

       

      I had 6400AAKSx4 Raid0 but not have the problem.

      How I resolve it?
